REVOLVING DOUBLE TRAFEZE.

EBPECEFICATION forming part of Letters Patent No.300,%87, dated June 17,188%.

(No model.)

To @ZZ whom z5 may concern,.-

Be it known that l, EDWARD J. Lia-AMY, of Syracuse, in the county ofOnondaga and State or New York, have invented a new and ImprovedRevolving' Double Trapeze, of which the following is a full, clear, andexact description.

The object of my invent-ion is to provide a new and improved doubletrapeze adapted to he revolved on its transverse central axis.

The invention consists in a centrally-pivoted frame provided with meanson one of the pivots for revolving` the frame, from each end otf` whichframe a trapeze is suspended.

The invention also consists in parts ot' construction, and details andcombinations of the same, as will be fully set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar' letters of reference indicatecorresponding parts in both the iigures.'

Figure l is a perspective view of my improved revolving double trapeze.Fig. 2 is a longitudinal sectional elevation of the journalboxcontaining the mechanism for revolving` the trapeze-frame.

Two trussed frames or side bars, A, have their ends united by transversebars B, forming a quadrilateral frame. Each side bar is provided at itsmiddle with an outwardly-projecting; pivot, C, which pivots arejonrnaled in the lower ends of the Shanks of an inverted- U -shapedframe, F. O ne of the shanks of the frame F is provided at its lower endwith an eye, c, or with an ordinary bearing, and to the lower end oftheother shank a casing, D, is secured, in which the corresponding pivot,C, is journaled. A worm-wheel, E, contained within the easing D, ismounted on the corresponding pivot, C, and engages with a worm, G,secured on a vertical shaft, G', mounted in the casing D, from whichshaft G a rod, H, extends upward parallel with the corresponding,` shankofthe frame F. Theframe F is suspended from wires or cables J, securedto its cross-piece and passed through the ceiling K, and the said 'frameis braced by means of wires or cables L, secured to the upper and lowerends of the shanks ot the frame. The upper end of the rod H alsoprojects through the ceiling K, and is provided at its upper end withmeans for turning it either by hand or by machinery. On each cross-bar Btwo rings, M, are held to turn between suitable collars or annularridges, which rings are provided with eyes or loops b, in which theupper ends of the ropes ot' a t apeze, N, are fastened.

l n place ot' pivoting` the quadrilateral frame in the ends ot' theshanlrs of the U-shaped frame F, the said 'frame can be pivoted in anupright frame or on standards; but in all cases one of the pivots is tobe provided with means for turningr the frame.

The apparatus is operated in the following manner: Each trapeze ismounted by a performer, and the quadrilateral frame is revolved slowlyon its central transverse axis by turning,` the shalt H, whereby theworm G will be turned and will turn the wheel E and the pivot C, onwhich the said wheel is mounted. The trapezes at all times hangvertically from the cross-bars B, and the performers can perform on thetrapeze in the same manner as on a stationary trapezc, the featsperformed being of a somewhat different nature, as thetrapeze-supporting frame revolves. The audience does not sce themechanism for revolving the trapeze-franie, as it is concealed by thecasing` D. If but one performer is to perform on the trapeze-fraine, oneend of the frame can be balanced in some suitable manner.

The trapeze can be of any desired shape, style, or construction.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination, with a frame adapted to revolve inthe vertical plane, of trapezes suspended from the said frame,substantially as herein shown and described.

2. The combination, with a revolving frame, of trapezes suspended fromthe same, substantially as herein shown and described.

3. The combination, with a cent Ially-pivoted frame, of means forrevolving the same, and of trapezes suspended from the said frame,substantially as herein shown and described.

4. The combination, with a revolving frame, of means for revolving` thesame, contained in one of the journal-boxes, and oi trapezes suspendedfrom the said frame, substantially as herein shown and described.

5. The combination, with a. revolving frame, of aworm-wheel mounted onone of the pivots, a worm engaging with the worm-wheel, a rod IOC) forturning the worni, and a casing' surround each having a central pivot,C, of the crossing` the `Worm-Wheel and Worm, in which casbars B, theWor1n-wheel E, mounted on one of ing the said pivot is journaled,substantially l :1s herein shown and described.

6. The combination, with the side bars, A, provided at the middle withoutwardlvprojecting pivots C, of the cross-bars B, the Worinwlieel E,mounted on one of the pivots C, the Worm G, engaging with theWorm-Wheel, the casing D, and the frame F, substantially as herein shownand described.

7 The combination, with the side frames, A,

worm-wheel, ,the frame F, and therod H, extending upwardly from the WormG, parallel with and adjoining the corresponding shank of the frame F,substantially as herein shown and described. p f ED WARD J. LEAMY.Witnesses: w
